Decimation Filter与数字控制振荡器是两个不同的概念。以下是关于两者的详细解答：数字控制振荡器： 作用：在正交数字下变频器中起着关键作用，用于生成理想的正弦和余弦波，以提供可变频率的正弦波样本。 工作原理：在高速信号采样频率情况下，NCO通常采用查表法，通过输入的相位数据来寻址查表输出相应的...
CIC滤波器主要由两个部分构成：积分器和梳状滤波器的级联。这种设计的冲击响应如图5所示，其频谱图揭示了其频率响应特性。CIC滤波器的所有系数都设置为1，这使得实现过程极其简单，无需进行任何乘法运算，且不需要存储滤波器系数。为了增加阻带衰减，通常会使用N级CIC滤波器，如图6所示。这种多级配置能够更...
PROBLEM TO BE SOLVED: To provide a decimation filter that reduces a loopback noise to a signal band and to promote a steep cut-off characteristic without increasing the scale of the filter circuit due to the order of filter coefficients and bit accuracy or the like.KASAI HIROYUKI...
Setting decimation filter to anything other than 1 distorts pointcloud in a very weird way. It appears that all the points are transformed to positive xy coordinates and/or removed. I have plotted a histogram of all point xyz coordinates...
A decimation filter has: a plurality of calculating devices each having a multiplier and an accumulator; a plurality of coefficient memories (a ring memory and shift registers) which store filter coefficients, and which correspond to the calculating devices, respectively; and a selector which sequent...
下变频器的结构与组成如图1所示，主要包括四个关键组件：量化后的中频数字信号、数字控制振荡器、CIC抽取滤波器、HBF抽取滤波器以及FIR低通滤波器。这一设计与讨论的重点集中在数字下变频部分，即如何通过这四个组件有效实现信号的下变频过程。数字控制振荡器产生本地数字载波，与量化后的中频数字信号进行混频...
